Log Data with NodeMCU and Google Sheets

Most of the time, the data from a sensor in an IoT application needs to be recorded. This data logging is important for later statistical analysis now most popularly known as data analytics. In this tutorial, we will record the data captured from the sensor to a spreadsheet. Let's build a NodeMCU Google Sheets data logger!

Intro to NodeMCU and Arduino IDE

node mcu v1.0

NodeMCU is a development board featuring the popular ESP8266 WiFi chip. As it turns out, you can program the ESP8266 just like any other microcontroller. Its obvious advantage over the Arduino or PIC is that it can readily connect to the Internet via WiFi. However, the ESP8266 breakout board has limited pins although the chip itself has a lot of …
